A display test apparatus includes a measuring apparatus and a calculating device connected to the measuring apparatus. The measuring apparatus provides a sample pixel value to a first display device including a first display panel, measures a first color coordinate value of an image displayed by the first display panel in response to the sample pixel value. The calculating device generates a first parameter of the first display panel in response to the first color coordinate value, generates a target color coordinate value in response to the sample pixel value, and generates a first mapping table in response to the first color coordinate value, the first parameter and the target color coordinate value.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The display test apparatus of claim 1, wherein the calculating device is further configured to provide the first mapping table to the first display device, and provide the second mapping table to the second display device.
5. The display test apparatus of claim 1, wherein the first mapping table includes a first converted pixel value corresponding to the sample pixel value, the second mapping table includes a second converted pixel value, different from the first converted value, corresponding to the sample pixel value.
6. The display test apparatus of claim 1, wherein the measuring apparatus is further configured to provide a display brightness value to the first display device and the second display device, measure the first color coordinate value further in response to the display brightness value, and measure the second color coordinate value further in response to the display brightness value.
8. The display test apparatus of claim 1, wherein the first color coordinate value is different from the second color coordinate value.
9. The display test apparatus of claim 1, wherein each of the first display panel and the second display panel is one of an organic light emitting display (OLED) panel and a Micro light emitting display (LED) panel.
13. The method of claim 11, wherein the mapping table includes a converted pixel value corresponding to the sample pixel value.
18. The method of claim 17, wherein the first color coordinate value is different from the second color coordinate value.
19. The method of claim 15, wherein each of the first display panel and the second display panel is one of an organic light emitting display (OLED) panel and a Micro light emitting display (LED) panel.
20. The method of claim 15, wherein each one of the first target color coordinate value and the second target color coordinate value is included in a given color gamut.
